We have been coming here for 14 years and it is still a fav.
I believe that they do brunch on the weekends but the best thing to come here for is their homemade ice cream.
Demetre's desserts are the best. My fav is their Peanut Better Ice Cream in the Nut Job sundae. Put chocolate nut, chunks, fudge sauce and the ice cream together and you have a wonderful dessert.
You can get crepes or waffles and ice cream too We have had them before also and I have never been disappointed. The Tiramisu and Chocolatta ice cream flavours are also great.
They do have cakes and pies here also -- my niece raves about "The Fridges of Madison County" - which is a triple layer chocolate cake with chocolatta ice cream. I have never attempted it personally -- too close to the ledge! haha
If you want some really creamy ice cream served up in lots of inventive ways, check out Demetre. They have multiple locations across the GTA also.
They do a variety of types of coffees too. Enjoy!
